While Jackman has done pretty good working wtih the material he was given, I don't think he was entirely right for the role. For most of his existence, Wolverine is supposed to be around 5'3". In the last 10+ years, he isn't generally protrayed as being that short in the comics.
I would, however, have liked to seen a much shorter man be cast as Wolverine. Jackman is listed at 6' 2 1/2". I would have liked to have seen a much shorter man's take on the role.

Marvel sold the rights, so there's nothing they can do about it. Besides, why would you want to see a midget with claws fight onscreen. Or a suit like he wears in the comics. It would look ridiculous and nobody (the general audience who know almost nothing about him) will take the character serious. Sabretooth (X1) was taller than Jackman so he was still a runt.
